5 year old Dell optiplex,intel pentium 4, eset nod 32 antivirus.
locks up and you do the control/alt/delete it pops up with no close box.
It doesn't have a close x on the top of the device manager or any other marks, it is a total blank line and no box on the bottom toolbar to right click it and close. So you have to shut it down. Any ideas? It has xp pro sp1,2 and 3. For a friend . the only thing i could find was a conflict or something with norton and Sp3 . not the problem .
Thanks .
